ONEUP COMPONENTS DROPPER SEAT POST

ONEUP YOUR BIKE

When we talk about OneUp, we're not talking about hitting a brick and getting a green mushroom, we're talking about exceptional dropper seat posts. The OneUp Components Dropper Seat Post is a one of a kind dropper seat post that is highly versatile. OneUp offers the world's shortest, long travel dropper post. This means it has the shortest stack height and effective length of any equivalent travel dropper post. This means you don't have to settle for a 125mm dropper post, you can now get a 150mm or 170mm dropper. The OneUP dropper is also tuneable so you can have custom drop lengths. Want your 170mm dropper post to be a 120mm dropper post instead? That's perfectly fine. The drop tuning can be done on the bike while you're out on the trail. It's tool free and can be done without removing the saddle or reaching for your shock pump. The OneUp dropper post requires no bleeding since it is cable actuated. The cable clamps at the lever which makes shortening the housing incredibly easy. If you're looking to breathe an extra life into your mountain bike, then get a OneUp Components Dropper Seat Post.

Major Negatives- The Green Actuator at the bottom sticks out 32mm and the cable comes out through the center. The seattube on my bike has a kink to it that prevents the use of longer droppers. You need to make sure you have 32mm + about 10mm more to ensure it clears the seattube or linkage bolts as it prevents proper function of the dropper. Thus, the total stack height of a 170mm dropper including the actuator and 10mm of clearance it requires is about 490-495mm.

Anyways, I currently had a 150mm Reverb that was inserted ALL THE WAY into my seat tube and with the 170mm Oneup, I'll have to shim it down to 145-150mm which is a bummer. If they would have located the actuator on the front side of the shaft, it would have a better chance of clearing the seat tube and allow deeper insertion.

Jenson's doesn't allow you to modify your review so I had to post a follow up review here regarding my initial 3 star review. Everything I mentioned in my 3 star review is still accurate however I discovered a hack that allows you an extra 3/4" insertion. Basically, the two cable housings that comes with the dropper is a metal housing. Sticking it in underneath the green actuator is causing the extra 10-15mm of length needed after the actuator. By just ditching the metal cable housing entirely, the cable is allowed to bend out of the way of the seat tube or seat tube bolt allowing you to stick the dropper further into the seat tube by about 1/2"-3/4". In my case, the dropper ended up being just 5mm too tall rather than 20mm too tall. So rather than get the shim that's currently out of stock, I ordered a Selle Italia SLR saddle that has a 6mm lower stack height than almost all other saddles which allowed me to use the full 170mm travel (actually 166-167 when measured).

Whoa, we'd love to see more pics and a ride report on how this works. I just got to try this post out myself. Keep Pedaling! skendall@jensonusa.com

Fantastic dropper at an incredible price

I purchased the 170mm OneUp dropper to replace a 125mm Fox Transfer that came on my bike. I wasn't sure I'd get all 170mm of travel, but found that due to the shorter overall height of the OneUp I was able to run it without shims and stay clear of the max insertion for my frame. Sweet!

Pros- Price, of course.- 170mm of drop makes the seat just disappear.- Very smooth operation. Quieter than the Transfer.

Cons- Haven't found one yet.

I've been on a few rides, crashed and twisted my seat around and have had no issues with it. I'll recommend this dropper to anyone.

Super easy install in conjunction with Oneup lever. Seem well made and a great value. On the trail compares well with Reverb that I used on another bike. Action is smooth and predictable with the lever vs. the plunger design on the Reverb. Quality seems high with only about 50 miles ridden so far it has worked perfectly with little/no perceptible side to side play in the saddle.

Good dropper but I'm questioning its performance when used in a steel frame

This is my first dropper post. I purchased after reading all of the great reviews of the dropper and oneup components in general. It was easy to install. I purchased the oneup lever to pair with this as well. My only concern at the moment is that I've lost rebound speed and sometimes it doesn't fully extend all of the way up since I've had to tighten the seatpost clamp enough to keep the post from moving side-to-side unintentionally while pedaling. I don't have a wrench with kN reader, so I figured to tighten it until the post doesn't move side-to-side easily, which when set this way, i get the results mentioned above. I'm wondering if my steel frame requires more torque force to keep the post from moving side-to-side compared to an aluminum or carbon frame? Maybe increasing PSI in the internal airspring will help? I set it to 285 psi, but haven't tested with the 300psi max yet.

Hello, over-tightening your seat clamp/collar can have negative effects on dropper posts performance. I'd recommend using a carbon paste. This will provide more friction with less clamping force. Keep Pedaling!

Working well

So far so good. It is very sensitive to seat clamp pressure, so definitely use a grip paste. The pressure is tough to get just right when removing the shock pump. Also, why would the super cheap plastic shim not come with it?

Wanted a 170 dropper and the One up droppers price was the best. Have had other products from them and they were all solid and worked well. Installation was the easiest of any dropper I’ve worked with so far and took maybe 30 minutes. So far performance is great and digging the 170mm drop on my 29er. Hoping it is as reliable as the other products I’ve used from One Up. Peace out

First dropper install. No info given with package but a quick trip to the web and easy as she was installed and is working as well as any other I've ridden. Good price, great product, and awesome company

Got the 170mm for my 2017 Stumpjumper 29 size large. The lever is in the perfect position. The return speed is quick and I have zero movement in the head. Install was pretty easy, the o-ring that holds the cable on fell off when I installed the and the cable was a bit tricky but when I put a tighter o-ring, it worked perfectly.

Great dropper post (no height tuning shims available as of April 2018)

First impressions - operation is completely smooth and I feel no play at all. Quite wonderful. Just what I need.

I primarily bought this because of the tunable stack height (my seat tube comes up a little too high for any other post besides a Gravity Dropper).

However: as of April 2018, the shims for tuning stack height are not yet available. So, you cannot do that adjust til "mid-May" per the company rep. Currently, they don't plan to put a shim in the box, instead you may have to buy a three-pack as an accessory (I'd suggest they give you one shim at the least).

I installed with a Fox Transfer 2X/3X lever and that worked out fine. Used a tiny dab of silicone caulk on the Fox cable ferrule that seats to bottom of post mechanism - just to hold in place while installing - not at all required for operation.

In all, a great product at a great price. I'm really happy with the buy.

I have always been in between dropper sizes. With the short length bottom section I was able to run a 170mm dropper and it fits both me and my intense Carbine perfect. It’s very lightweight and you can adjust travel to any length you need with just a shim and a pair of scissors, the lever design is great too. Actuation is very smooth and just the right speed. Oneup nailed it with this dropper A+++++++

I switched from a Reverb dropper post and this has been a brilliant upgrade. It took minutes to install, has no fluid to bleed, and it just seems to function smoother, faster, and better. Plus, being from the Midwest and riding on cool fall days caused the Reverb to get stuck in the down position a couple of times, and that isn't possible with this one.

I recently rented a couple of bikes on travels, and I preferred OneUp's dropper over Specialized and KS posts that were on those bikes.

Unless this develops some kind of issue way down the road, I only see upsides from this post. Nice work OneUp.

This post is rock solid. When you stop the post in its travel, it locks positively into place without any sag. It is brand new so there is no wiggle at the nose of my saddle, but time will tell on that. The best part about this post, I can run a 170mm on my frame rather a 150mm. It is super smooth up or down and I would say it is very comparable to a Fox Transfer in functionality. There is no reason to ever consider an on sale Reverb ever again. My only gripe is that I am currently running a Transfer remote rather than a OneUp. The ergonomics on their remote is better than anything else on the market.

I had a long talk with the reps at Sea Otter about the differences in latest dropper posts on the market. After our discussion I decided to cancel my order for the Transfer and snag a OneUp at about $100 less. I feel like with the price point OneUp came in at, the others are going to have to step their game if OneUp can keep their inventory high enough for demand.

I got the 170mm w/the wolf tooth light action remote (wolf recommends the reg action, but mine works amazing). Install was super easy smooth. I only have 1 ride but I am loving the 170mm drop vs my 125mm reverb. The actuation is super smooth and easy, so much better than the plunger. It comes up quickly with a solid thump, not a bang or clank like the reverb.

I have had this dropper for a month now and it has been great. I used to have ks Lev dx dropper and it was very good as well so I can compare between the two. The One Up dropper is easy to install and has worked flawlessly. Things to be aware of are.... The return speed is fairly quick so watch out for those delicate parts. I believe this is adjustable via air pressure but not sure positive about that. Finally the only thing that I have had to get used to is that if the seat is loaded it takes the full pull of the lever to get it to drop. If you are standing and then sit down it only takes about 3/4. Pull. Anyways just buy it you will love it.

I've had this post for a few months now and have been pretty happy with it. The post has smooth operation and fit well in my 2016 Specialized Enduro. I am still not sold on the infinite settings, but can appreciate the feature at times. My old command post was loud when it came all the way up so I knew it was all the way up, this post is very quiet on when it reaches the top. The air valve is under seat post clamp so it ever needed to be adjusted you will have to remove your seat. Over all the seat post is one I would recommend, it has plenty of travel, smooth operation, shorter insert to fit wider variety of frames, and very reasonable price.

So far so good as far as dropper post goes, however apparently their dropper lever is flawed design and breaks. I posted two reviews on their website and they didnt post my review. I do give them good review because their warranty is great.

Well made and like everything OneUp does it's well thought out. Been working great so far. My only complaints are you need to remove the saddle to adjust air pressure but that's a once a year thing so no big deal. I've had some trouble in below freezing conditions lately but did some maintenance tips from OneUp so hoping that solves things.

Also I suggest clamping the seat collar at 3-4Nm. Any more and the post doesn't return freely.

I've only had the post for the weekend, but initially this is a great post for the money! The post is smooth and swift, no play at extension or fully dropped. The lever is easy to setup and well placed. I ended up using the full travel due to the short stack, so I have no need for a shim. My only gripe and the reason why I gave it 4 and not 5 stars is that the travel measures 162-163mm and not 170mm. Not a huge deal but it still came up a bit short. We'll see how reliable the post is over the summer of abuse.

Install was quite simple, good thing as there really is not any documentation. Maybe that comes with the lever.

The key fact is that it allows longer dropper install on constrained bikes. I was able to move from a KS Lev 150 to the OU 170.

One small issue was that the head bolt on the front stuck up too far on my bike with a slack seat tube. (2017 Trek Fuel) Grinding 5mm off the bolt fixed the issue. OneUp responded right away to my inquiry about bolt length. They did not fix it, I did, but they were reachable, which is great.

The post is not as smooth as the KS but it is very effective and a huge plus is that it has no play at all. I hope it stays that way!

Got this post two weeks ago. Used it serveral times in warm weather without any issues. Unfortunately it stopped working that well this weekend in Ashland when the temperatures dropped (around 40°). It would only come up half way when pushing the leaver. I had to reach down several times to fully extend the post again..

Purchased the 150 dropper post for my XL trail bike. I picked oneup for the low price and high travel options, along with the short stack height of the post for my XL bike. Install instructions were not included but it was pretty straight forward.

The product meets all the conditions and characteristics of the brand. It works excellent, it is easy to install and the price is clearly the best in the market. has nothing to envy to Reverb or Bikeyoke. Very happy with the purchase.

First off I wouldn't recommend this for an older Specialized Enduro (2014). You'll have to drill a hole in the frame for the cable, which is what I did (near the bottom bracket).I just installed this post but my initial experience/install experience is not good. The insertion depth of the 150 is slightly too long for my medium frame, if I push the post down any further it presses the actuator against part of the suspension linkage axle that goes through the seat tube. Next, tightening my seatpost clamp just barely enough to keep the post from slipping is still too tight for the post to work properly. I think I have some fiber grip somewhere but I'm sure the collar isn't torqued as high as it is speced.

Can you use a remote other than the oneup proprietary version?

BEST ANSWER:The cable is crimped at the remote for this post. This makes setup super simple. You can use any cable remote that allows you to clamp the cable at the remote. We've been stoked on the Wolf Tooth option, but this new version from OneUp Components looks great too. Keep Pedaling!

BEST ANSWER:Typically that’s not the case but if you have a frame that has the ability to run in turn on the route of cables you can do it it’s never easy to do but if you have the hole in the frame For the cable to run from the handle bar and into the framing up the center of the seat tube you can do it but you might want to have somebody look at your bike.You could always buy a next ternal he routed seat post drop her most brands make a next ternal version of it However I don’t believe oneup components makes one

You will have to modify your frame to allow it to work. After buying this post, I drilled a small hole in the back of the seat tube to allow my old internal post to work on my wife's 13 Specialized Safire Expert which came with an external dropper and it turned out great.

BEST ANSWER:No. The cable is oriented in the opposite direction.In the Race Face post, the bulbous cable end is at the lever, while the One Up has that end at the base of the post.There are some other levers that use this design such as the Fox Transfer lever.

I do not believe so. The Race Face dropper has the cable barrel on the lever side, while the one up (and fox and a few others) has the cable barrel on the dropper side, and just uses a pinch bolt to hold / set initial cable tension on the lever side.

BEST ANSWER:Yes, it will! The remote cable knurl seats at the post end and the cable is clamped at the remote, just like the Fox. This post is a great feeling post, and has a heap of cool features at a killer price.

BEST ANSWER:max insertion length is just the post itself. If you look on the manufactures website the max insertion for 150 mm post is 223mm and for the 170mm it is 243mm but the actuator is an additional 32mm for both.
